Published in Guide to Digital Infrared is a page of retina-grade examples with the Nikon D800-IR+ Zeiss 15mm f/2.8 Distagon in both false color and monochrome.
The Nikon D800-IR used here was by MaxMax.com and is for sale from them. See the details on the first look page.
Some people find images in IR of people disturbing (morbid or ghostly?). I am not holding this one out as something I like, but purely as an example of the look that IR can produce as it sees into skin more than visible light.
